Answer:

<h2>a = 2 and b = 6.</h2>

Step-by-step explanation:

The equation is given by 10x - 4 = ax + b\\(10 - a)x = 4 + b\\x = \frac{ 4 + b}{(10 - a)}.

The given equation is a one degree polynomial, hence it has only one solution whatever the value of a and b will be.

If the value of a is 10, then the solution of the equation will be undefined.

Hence, a is any real number rather than 10.

As for example, a = 2 and b = 6.

(2 − 3)(1 − ) − (3 − )(3 + )
Lostsunrise [7]

Answer:

your equation is wrong!! the answer is 10

Step-by-step explanation:

the correct order of the equation is:

(2-3)(-1)-(-3)(3)

first, solve in the parentheses from left to right:

(2-3)(-1)-(-3)(3)=\\(-1)(-1)-(-3)(3)=\\1-(-3)(3)=\\

If we have 2 negative signs then we will change them to positive :

1-(-3)(3)=\\1+3(3)\\

now we have an equation with parentheses, we will multiply 3(3)\\ because the parentheses go first.

1+3(3)=\\1+9=10
